Sample space: tails/tails,tails/head,head/tails, head/head.
(the slash divides the first toss and the second toss)
P(head,head)=1/4
P(not tail,tail)=1-1/4=3/4
the probability is not the same.
12 more than the quotient of a number t and 7
is v
12 more than
the quotient of a number t and 7 = v (quotient means to divide)
12 more than t / 7 = v
Answer:
f(-4)=-32
Step-by-step explanation:
Plug in -4 for x
f(-4)=5(-4)-12
Combine like terms
f(-4)=-20-12
f(-4)=-32
The value of the expression 3ac - b² - c² is -61.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The expression will be solved as below:-
3ac - b² - c² = ( 3 x 4 x -3 ) - ( 4 )² - ( -3 )²
= ( -36 - 16 - 9 )
= ( -61 )
Therefore, the value of the expression 3ac - b² - c² is -61.
